There has happened something very strange on gluster03-mi. It contains the directory, but it's not the same one that there's on the other bricks (8 bricks have gfid a9d904af-0d9e-4018-acb2-881bd8b3c2e4, while that node has gfid bda849fc-a556-469e-ad84-ed074f2c1bcd) Whatever that has happened here has affected both bricks of that node in the same way. What return these commands on gluster03-mi: ls -l /brick1/recorder/.glusterfs/a9/d9/a9d904af-0d9e-4018-acb2-881bd8b3c2e4 ls -l /brick1/recorder/.glusterfs/bd/a8/bda849fc-a556-469e-ad84-ed074f2c1bcd ls -l /brick2/recorder/.glusterfs/a9/d9/a9d904af-0d9e-4018-acb2-881bd8b3c2e4 ls -l /brick2/recorder/.glusterfs/bd/a8/bda849fc-a556-469e-ad84-ed074f2c1bcd 2. It seems that node gluster04-mi has been stopped (or rebooted or has failed) while an operation that modifies the directory contents was being executed, so it has lost an update an it's out of sync (both bricks on the same server have missed one update, so it seems clear that it's not a brick problem but a server problem). The global result of all this is that you have 4 failed bricks on a configuration that only supports 2 failed bricks. BTW, having two or more bricks on the same server is not recommended because a single server failure causes multiple bricks to be lost. In this case a directory can be recovered, but if this happens to a file, it won't be 100% recoverable. Are there any files inside /Rec218 ? If you are going to delete the directory and all its contents and brick contents in gluster03-mi are the same than in other servers, the following commands should be safe (otherwise let me know before doing anything): Before starting you must be sure that nothing is creating or deleting entries inside /Rec218. It would be even better if this could be done with volume stopped. On each brick (including gluster03-mi): setfattr -n trusted.ec.version -v 0x1 <brick path>/Rec218 On bricks in gluster03-mi: setfattr -n trusted.gfid -v 0xa9d904af0d9e4018acb2881bd8b3c2e4 <brick path>/Rec218 setfattr -n trusted.glusterfs.dht -v 0x000000010000000000000000ffffffff <brick path>/Rec218 On client: check that the directory is accessible and its contents seem ok. If so: rm -rf <mount point>/Rec218 If you have a way to reproduce this situation, let me know.
